Frequently Asked Questions

Do I have to deactivate Office 2016 on my old hard drive before reinstalling?

If the old hard drive is dead, formatted, or removed, you do not need to deactivate it manually. Microsoft's activation servers will typically recognize the hardware change. If you encounter an activation limit error after reinstalling, you may need to complete the activation via phone support.

Can I install Office 2016 on a new hard drive without a Microsoft account?

No, Office 2016 requires a Microsoft account for the initial setup and download. If you used a physical product key originally, it was linked to the Microsoft account you logged into during that first activation.

Will I lose my old Word and Excel files when installing on a new hard drive?

The Office 2016 installer only restores the applications themselves. To recover your old files, you need to transfer them manually from your old hard drive (if it is still readable) or download them from a cloud backup service like OneDrive.
